I-SSD vs HDD: Yeyiphi ekulungeleyo?

Yintoni umahluko phakathi Ssd kunye neHdd? I-Solid State Drives (SSDs) kunye ne-Hard Disk Drives (i-HDDs) inokwabelana ngokufana ngokomzimba, kodwa iindlela zabo zokugcina idatha zihluke kakhulu. Uhlobo ngalunye lokuqhuba lunezinto zalo eziluncedo kunye nezingeloncedo, kwaye ukugqiba ukuba yeyiphi ekufaneleyo kux主页keke kwindlela oyisebenzisa ngayo ikhompyuter yakho. I-HDD yethu vs. Isikhokelo se-SSD sichitha ukusebenza kohlobo ngalunye lwe-drive yokugcina kunye neempembelelo zabo kuwe.

IiHDD zisebenza njani:

Ii-HDD zizixhobo zokugcina ezintsonkothileyo eziqulathe iipleyiti ezinobuthathaka obunamandla, ingalo ye-actuator eneentloko zokufunda/zokubhala, kunye nenjini yokujikeleza kwepleyiti. Ukulawulwa ngumlawuli we-I / O kunye ne-firmware, ezi ziqhuba ziququzelela idatha kwiingoma ezigxininisiweyo kunye namacandelo. Ukubhala i-algorithms inkqubo yedatha ngaphambi kokugcina, ukuvumela i-firmware ukuba ibone kwaye ilungise iimpazamo. I-preset platter speeds, ukusuka kwi-4200 ukuya kwi-7200 rpm, ichaza ukusebenza kakuhle kokubuyiswa kwedatha kunye neenkqubo zokubhala kwii-HDD.

Inkqubo yokuFunda/Bhala:

Ngalo lonke ixesha ucela ikhomputha ukuba ifumane okanye ihlaziye idatha, umlawuli we-I / O uyalela ingalo ye-activator apho idatha ikhona, kwaye iintloko zokufunda / ukubhala ziqokelela idatha ngokufunda intlawulo kwidilesi nganye. Ukuba isicelo sibandakanya uhlaziyo lwedatha, iintloko zokufunda/ukubhala ziguqula intlawulo kumkhondo ochaphazelekayo kunye necandelo.

Imiqobo:

Amacandelo omatshini asetyenziselwa ukufunda nokubhala idatha kwii-HDD zikhokelela kwixesha elide lokubuyisela xa kuthelekiswa neendlela zombane. Iindawo zoomatshini zisesichengeni sokonakala xa ziphathwa kakubi okanye ziwisiwe, ngakumbi kwiilaptops. Ii-HDD nazo zinzima kwaye zidla amandla amaninzi xa kuthelekiswa ne-Solid State Drives (SSDs).

Izibonelelo zeeHDDs:

Ii-HDD zitekhnoloji ezizanyiweyo neziyinyani, zihlala zinoqoqosho ngakumbi kunee-SSD zomthamo ofanayo wokugcina. Okwangoku, ii-HDD zibonelela ngeendawo ezinkulu zokugcina kunee-SSD.

Yintoni i-SSD (i-Solid State Drive)?

Ii-SSD zisebenza njani:

Ii-SSD zisebenzisa imemori edanyazayo, ngakumbi itekhnoloji ye-NAND, ekusebenzeni okugqwesileyo kunye nokuqina. Ngokungafaniyo nee-HDD, ii-SSD azinamalungu ashukumayo, ukomeleza ukuqina, ukusebenza kumaqondo obushushu asezantsi, kunye nokusetyenziswa kwamandla amancinci. Umsebenzi we-NAND ubandakanya iintlawulo zokurekhoda ii-transistors zokugcina idatha kwisakhiwo sebhloko esinegridi. Umlawuli we-SSD udlala indima ebalulekileyo ekulandeleni iindawo zedatha.

Inkqubo yokuFunda/Bhala:

Kwii-SSD, ukuhlaziywa kwedatha kunzima kakhulu. Xa nayiphi na inxalenye yebhloko ihlaziywa, yonke ibhloko kufuneka ihlaziywe. Idatha esuka kwibhloko endala ikopishwa kwibhloko eyahlukileyo, ibhloko iyacinywa, kwaye idatha iphinda ibhalwe ngotshintsho kwibhloko entsha.

Nanini na xa ucela ikhomputha ukuba ifumane kwakhona okanye ihlaziye idatha, umlawuli we-SSD ujonga idilesi yedatha eceliweyo kwaye ufunda ubume bentlawulo.

Ngexesha lokungenzi nto, inkqubo ebizwa ngokuba yingqokelela yenkunkuma iqinisekisa ukuba ulwazi kwiibhloko ezindala luyacinywa kwaye lulungele ukubhalwa kwakhona. Kukho inkqubo ebizwa ngokuba kukucheba, ukwazisa i-SSD inokutsiba ukubhala kwakhona idatha ethile ngexesha lokucima ibhloko. Oku kubalulekile ukuthintela ukunxiba kwangaphambi kwexesha kwi-drive, njengoko ibhloko nganye inenani eliqingqiweyo lemijikelo yokufunda/yokubhala.

Ukuqhubela phambili ukunciphisa ukunxiba, i-algorithm iqinisekisa ukuba ibhloko nganye kwi-drive idlula inani elilinganayo leenkqubo zokufunda / zokubhala. Le nkqubo, eyaziwa ngokuba ngumgangatho wokunxiba, yenzeka ngokuzenzekelayo njengoko i-drive isebenza.

Njengoko iinkqubo zokufunda/ukubhala zibandakanya ukunyakaza kwedatha, ii-SSD zihlala zibonelela ngendawo yokugcina isibonelelo. Inani elithile lokuqhuba alixelwanga kwinkqubo yokusebenza kwaye ayifumaneki kubasebenzisi. Oku kubonelela ngesithuba sokuqhuba nokucima izinto ngaphandle kokuchaphazela umthamo wogcino jikelele.

Imiqobo:

Ii-SSD ziteknoloji entsha, kungoko zibiza kakhulu kune-HDDs. Nangona ukubamba, ukufumana okuphezulu-Umthamo Ssds inokuba ngumngeni ngakumbi xa kuthelekiswa neeHDDs. Ii-HDD zinokunikela ukuya kuthi ga kwi-2.5 yamaxesha amandla e-SSD.

Izinto eziluncedo kwii-SSD:

Kutheni ukhetha i-Solid State Drive? Ii-SSD zinokunyusa isantya sokulayisha semidlalo, usetyenziso, kunye neemuvi. Ngenxa yetekhnoloji esetyenzisiweyo, ii-SSD zikhaphukhaphu, zikwazi ukumelana nokunyakaza kunye nokuhla, kwaye zisebenzisa amandla amancinci, okukhokelela kubushushu obuphantsi bokusebenza.

Enye yeenzuzo ezibalulekileyo zee-SSD:

Ngaba isantya sabo esikhawuleza kakhulu xa kuthelekiswa neeHDD. Umzekelo, uthotho lwe-G-BONG X, i-NVMe SSD yethu ekhawulezayo, ibonelela ngesantya sokufunda/sokubhala esichukumisayo ukuya kuthi ga kwi-3400/3000MB/s. Nditsho nee-SSD eziphathwayo zidlula ii-HDD. Ngesantya sokufunda ukuya kuthi ga kwi-1050MB/s kunye namandla ukuya kuthi ga kwi-2TB, i-X8 inamaxesha angama-100 ngokukhawuleza kune-USB flash drives kunye namaxesha angama-7.5 ngokukhawuleza kuneediski zemveli.

Isigqibo

Umahluko phakathi kwee-hard drives kunye ne-slid state drives kwiteknoloji esetyenziselwa ukugcina nokubuyisela idatha. Itheyibhile engezantsi ibonisa ezinye zeeyantlukwano.

IiHDD zitshiphu kwaye unokufumana indawo yokugcina eyongezelelekileyo. Ii-SSD, nangona kunjalo, zikhawuleza ngokukhawuleza, zikhaphukhaphu, zihlala ixesha elide, kwaye zisebenzisa amandla amancinci. Iimfuno zakho ziyakuyalela ukuba yeyiphi idrayivu yokugcina eya kusebenza kakuhle kuwe.
